PRESS FOR EXTRACTING OIL FROM LINSEED.

Specification of Letters Patent N 0. 19,708, dated March 23, 1858.

To all whom it may concern:

Be it known that I, CHARLES Moonn, of Trenton, in the county of Mercerand State .of New Jersey, have invented certain new and usefulImprovements in Presses for EX- tracting Oil from Prepared Linseed andOil and other Fluids from other Substances and for other Purposes; and Ido hereby declare that the same are described and represented in thefollowing specifications and drawings.

To enable others skilled in the art to make and use my improvements Iwill proceed to describe their construction, use and operation referringto the drawings in which the same letters indicate like parts in each ofthe figures.

Figure 1 is an elevation of a press with my improvements. Fig. 2 is aplan. In each of these figures some parts are represented as broken awayto show others in section.

The nature of my invention and improve ments in presses consists inmaking grooves in the plates placed between the layers of substances tobe pressed, so arranged as to conduct the oil or other fluid pressedfrom the substances on each plate to its proper destination without itsrunning onto the plate below and further in fastening the hair cloth orpadding to the plates of the press, so as to dispense with the leatherentirely, to which the hair cloth or padding has usually been fastenedheretofore, and in maln'ng a thick edge about two and a half inches widearound the hair cloth or padding by doubling it .over or weaving itthicker, so as to press the oil out of the edges of the cloths, whichcover the cakes or substances pressed. Also in connecting the upperplate to the top of the press by links or staples and pins and theplates to one another by links and pins, so arranged that the plates maybe pressed together without cramping the links by which they areconnected.

In the accompanying drawings A, is the floor or foundation on which thebot-tom B, of the press rests, to which bottom the standards C, C, arefastened which connect it to the top D, to which they are also fastenedto form the frame of the press as represented.

The bottom B, is provided with a hollow cylinder E, and piston F,similar to those in common use in hydrostatic presses, and intended tobe operated by a similar or such an apparatus as will answer thepurpose.

The bed G, of the press is fitted to traverse between the standards C,C, and is fastened to, and operated by the piston F, which is forced up,by forcing water into the cylinder under it, in the usual manner orotherwise.

There is a series of plates'I-I, H, H, which are made the same size ofthe bed G, and provided with pins or studs I, I, arranged as representedin the drawing, so that the upper plate may be suspended to the top D,by the staples J, J, and the next below it to the top one by the linksK, K, which links and staples embrace the pins I, I, in the plates so asto hang the plates in succession to the top of the press as representedin the drawing; the pins I, I, being so an ranged in the plates as topermit them to come together in the operation of pressing, and allow thelinks to traverse freely on the pins, without interfering with eachother. The plates H, H, may be made of such materials as will answer thepurpose, but

I prefer them when made of boiler iron five eighths of an inch thickwith grooves L, L, along each side and across each end, so constructedas to conduct the oil or fluid pressed from the substance on each plateoff at one end, onto the spouts M, M, which conduct it into aperpendicular trough which may be constructed with an opening in oneside for the ends of the spouts to traverse in, which trough conveys itto the vessel or reservoir prepared to receive it. The spouts M, M, aremade of sheet iron in the form represented with their edges turned up soas to conduct the fluid off as required, and there is a cleat N, of thesame material fastened to them so that when the edges of the spouts M,M, are put under the plates H, H, the cleats N, N, will project so farover the tops of the plates, as to hold the spouts in their properplaces without other fastening. The hair padding P, P, which permits theoil to escape from the substances pressed, is made of very thick haircloth, and the edges of the padding are made thicker or twice as thickas the other part, about two and one half inches wide along each sideand across the ends, so as to press the edges of the cloth clean, on thecakes of substances pressed. The edges of the padding may be madethicker by weaving the hair cloth from which it is made,

thicker at the edges and where it comes across the ends of the plates;or if the hair cloth is wove of uniform thickness the edges of the clothmay be doubled over and folded, so as to form the additional thicknessrequired on the edges of the padding, which padding may be fastened tothe plates with leather thongs put through holes in the plates for thatpurpose as represented at Q, Q, or fastened in some other convenientmanner.

The press having been constructed and completed as above described thepulp, or prepared linseed, or other substance, is covered with cloth andmade into cakes or spread in a mold with an open end so that the moldwith the pulp or other substance in it, can be put in between the platesof the press and the mold withdrawn so as to leave the pulp; and whenall the spaces between the plates have been filled the pump is set towork to raise the piston and press out the oil which is conducted off bythe grooves and spouts described. After the pulp is properly pressed,the water may be let out and the piston allowed to descend when thecakes between the shelves may be removed and more pulp supplied as abovedescribed. I contemplate -that the plates of the above described pressmay be hung with chains instead of the pins and links described.

The advantage of hanging the plates to the top of the press is a savingof one half of the labor of filling or clearing the press as the platesare not removed; and by fastening the padding to the plates the entireexpense of the leather heretofore used is saved. Also by grooving theplates and conducting off the oil, theexpense of the press boxheretofore used is saved; and by making the padding thicker at the edgesI dispense with the expensive knit woolen bags, and substitute commonsail duck, at one fourth of the cost of the bags; besides the edges ofthe cakes are pressed as dry and clean as any other portions, so thatthere is no occasion to press them over again.

I believe I have described the construction, operation and use of myimprovements, so as to enable any person skilled in the art to make anduse them.

I will now specify what I desire to se- 7 cure by Letters Patent, viz:

1. The combination of the grooved plates with the hair padding or suchother padding as may be used, fastened to the plates of the press withits edges made thicker than the body of the padding.

2. I also claim connecting the upper plate to the top of the press bylinks or staples and pins, and the plates to one another by links andpins, so arranged that the plates may be pressed together withoutcramping the links by which they are connected sub stantially asdescribed.
